• BB Cups are forged & CNC machined from 6066 aluminum.
• Features 35% more thread engagement & thicker walls than the XC/AM BB cups for greater durability in big-hit situations.
• Massive external bottom bracket cups house 35% larger ball bearings than internal systems, yielding vastly improved durability.
• Bearings feature a special “full-complement” construction. This doubles the amount of ball bearings in the cartridge & greatly increases it's load carrying capacity.
• Bearings feature our custom triple wiper seal to better retain grease & keep contaminants out.
• Bearings are factory filled with Phil Wood waterproof grease — tested & proven to extend bearing life.
• Interchangeable with select Shimano and FSA external MOUNTAIN BB systems.
• Fully serviceable with BBEXITOOL

This is the same bottom bracket that comes with the Race Face Diabolus cranks, so you know it's built to last, but what you might be unaware of is that the Diabolus cups have 100mm extra thread insertion. Not only does this reinforce the bottom bracket shell and reduce the risk of stripping, but it also gives you more scope for fitting chain devices to frames without ISCG mounts. Additionally, the Diabolus bottom bracket can be used for spacing out your BB shell so that you can run cranks designed for 83mm shell widths on standard 73mm bottom bracket shells. This improves the chainline with 150mm rear hubs without leaving your BB cups literally hanging on by a thread. Bearing life has proved reliable and you can't beat a splash of gold on the dirtiest area of the bike.
